Dr. Naresh Patel, neurosurgeon, diagnosed Holmes as having a Rathke's cleft cyst (RCC). The rare, fluid-filled sac grows near the pituitary gland at the base of the brain and eventually can cause hormone and vision problems. Dr. Patel joined forces with Drs. David W. Dodick, neurologist, and Michael D. Whitaker, endocrinologist, to work on Holmes' case.

Their further tests revealed an increase in the size of her cyst over a short period of time as well as progressively worsening vision. "I was concerned that the pressure on Shona's nervers was causing her to become blind," says Dr. Patel. "We needed to remove the cyst to save her vision."
